Pre-biased PNP in a tiny SC-75 — what it saves you
The BCR 153T E6327: The Infineon BCR 153T is a PNP pre-biased transistor in the SC-75 (SOT-416) surface-mount package. It integrates two 2.2 kΩ resistors—one in series with the base, one from base to emitter—so you drop two external passives per transistor. Collector current is rated 100 mA maximum, with a collector-emitter breakdown of 50 V. Saturation voltage is 300 mV at 1 mA base drive into 20 mA collector load. The 200 MHz transition frequency keeps switching edges clean in low-speed logic translation or relay-driver circuits.
Mounting and handling notes
The SC-75 package is small, so the solder-paste stencil aperture and reflow profile need attention to avoid tombstoning. The part ships in Tape & Reel (TR), ready for pick-and-place.
